ChuBu Diesel Heater 2KW/5KW/8KW 12V-24V Portable Diesel Air Heater with Muffler, Remote Control, LCD Monitor, Fast Heating Defrost Defog for Campers, Truck, RV, Boat, Garage

I recently purchased the 8KW model to heat my garage during the cold Montana winters, ensuring that my workspace remains warm enough for projects while also preventing freezing. Below is my detailed feedback on the unit’s performance, assembly, and usability.The Positives:- This heater operates efficiently, particularly on lower settings, making it highly fuel-efficient. The large fuel tank is a significant advantage over compact all-in-one models.- Assembly was straightforward, though users will need to determine their own mounting and exhaust routing solutions, as the unit is not self-contained.- The value is excellent—I was able to apply a $30 coupon, bringing my final cost to just $80.- In terms of heating performance, it effectively warms my 450 sq. ft. garage from the low 30s to 50°F within two hours on setting 6 out of 10. After reaching a comfortable temperature, I can lower it to setting 2 to maintain approximately 55°F.- The hidden settings menu can be accessed using the code 1234.- To switch to Fahrenheit, press and hold the down arrow for about three seconds before starting the heater.Areas for Improvement:- The instruction manual is not well-translated, though it generally conveys the basics.- The noise level is average—the blower fan is noticeable on higher settings but relatively quiet on lower ones. The fuel pump emits the characteristic diesel heater ticking sound, which may bother some users, but I personally don’t find it disruptive. The included rubber mount helps reduce noise but could be improved further, possibly by enclosing the unit.- This model takes up more space than compact units, but its flexibility in mounting is a plus. The larger fuel tank is particularly beneficial.- Priming the unit is not intuitive. Users need to press the up arrow until the screen changes, then enter the desired interval for the pump to run. I had to crack open the fuel filter to break the airlock and initiate fuel flow.- Included hardware is exclusively short self-tappers. Plan on needing some other fasteners and adhesive/sealant.Challenges and Considerations:- Remote Pairing: The process is not clearly explained in the manual. To pair, press the up button and the settings button on the controller (attached to the unit) simultaneously to enter pairing mode. Then, press the power and OK button on the remote at the same time until pairing is successful. This must be done before starting the heater.- Stated vs. Actual Power Rating: According to both the manual and the hidden settings menu, this unit is classified as a 5KW model (P1H2) rather than an 8KW model. From what I have read, the difference between 5KW and 8KW models is minimal, aside from the 8KW version sometimes running richer. While this has not caused issues for me, it does raise concerns about the accuracy of product specifications.- Fuel Line Issues: The soft rubber fuel line (labeled as the “short fuel line” in the manual) is too short. I barely managed to install it by mounting the tank directly behind the unit and utilizing every millimeter of the line. I recommend purchasing additional clear yellow tubing to simplify installation. Additionally, the included hard plastic “long fuel line” is too small to fit over any of the fittings, rendering it unusable.Overall, this heater offers excellent value and performance despite some challenges with instructions, installation, and fuel line length. I appreciate the product’s efficiency and heating capability, but clearer documentation and more accurate specifications would go a long way. I plan to eventually add an afterburner controller for additional features and will update this review at that time.

Have installed 3 of these now (two truck beds and a RV camper) and they work great. The amount of extra you get in this kit is worth the money. Couple of notes: Some models you can adjust the altitude to help with high elevations but also to run less fuel leading to less heat (these heaters can cook you in the back of a pick up bed with a cap even on the lowest setting at 35F outside...but I cannot find a way to change elevation on this unit. Buy better fuel line and connectors (Strongthium 3/16 Fuel Line Hose Kit for Scooters ATVs Dirt Bikes Mini Bikes & Go-Karts with 3/16 Gas Clamps Valve & Filters ), Buy better fuel filters (Universal Gas Inline Fuel Filters with Magnet for Motorcycle ATV Quad Go Karts Accessories 3/16 Inch (Pack of 10)) Buy a better muffler (24mm Exhaust Muffler Pipe Upgraded for Chinese for Eberspacher Diesel Heaters Air Compressor with 2 clamps and screws, Silver), Insulate the exhaust with fiberglass wrap if chance of touching it when installed. The pump is loud but most are.

This is a pretty nice heater for the price. I have a couple different versions of these heaters, and have buddies with similar, but different heaters. For the most part they are all the same, or similar enough that there's not much difference other than a few extra features in the controller. That being said, this one is also different in that instead of having the typical plastic shell, this one has an aluminum shell. Not sure if it matters in use but something worth noting. The accessories that came with this heater are pretty standard, including the duct work, splitter, two vents, etc. It comes with the bigger tank than others, which is also a nice feature. In use, it runs quiet and puts out a lot of heat. Running on setting 1 for a week straight, in 20-50° F temps, I was averaging about 1 gallon/day. Not sure if that's good or bad but seemed reasonable. The controller is middle of the road in terms of features, and the instructions are OK at best so surfing the internet provided more info. One thing that is annoying is that the instructions to get it into prime mode to charge the fuel system never worked, after dozens of attempts. Videos online also didn't work. I finally just kept trying to start it and eventually filled the lines and it fired up. This controller also doesn't have the ability (that I could find or get to work) to connect to my phone. I may revisit this at some point, but the included remote worked well enough that I didn't worry about it.All-in-all, this is a great heater that often goes on sale, and is worth the money if you're in the market.

Put the unit into service. It worked perfectly for three days and then produced an E8 code. And failed to produce heat. The manual gives trouble shooting instructions but I don’t feel like I should need to be disassembling the unit to check igniters or internal filters. The external filters is clear. The pump still moves fuel but the unit only produces smoke. If I was relying on the heater to keep me warm I would have froze to death on the third night

I purchased to install in a 10×20 workshop, and being skeptical of cheap Chinese diesel heater, i bought the absolute cheapest one i could find. $63 on a prime day sale. Adapted to 110v outlet, i absolutely love this thing. Controls are in Celsius, and take some learning, but ok. It has heated my small shop reliably all winter, I do have a wood stove, but there are times I don't have a lot of time avaliable in the evening to build a fire but still need to make some kind of repair on something. The clamps and fuel line are not that great, but the unit itself is amazing. I did have to purchase a longer exhaust pipe for my specific application, but that is situational dependant. No issues at all.
